In developed countries like the United States and European countries, the application of informationtechnology in the areas of government have been significantly in creating a clean government andtransparent. Some examples include the implementation of the model B2B (business to business ecommerce)applications for the procurement of goods and services electronically (e-procurement), theshort message technology to accelerate the delivery of information and web-services to facilitate otherparties to get information although different technology and platform.Meanwhile, in our countries, the application of information technology in the field of governance is stillvery limited. This is because the source of funds and skilled human resources are very limited. Someexamples of the application of information technology that is already there; Portal made for each office,portals for profile local government and application for one stop services. Most of the local governmentbuild the system information partially so can occurred distortions such as inconsistencies of information.Apparently there has been no local government in Indonesia that utilize ICT (information andcommunication technology) extensively to achieve good governance.It is time for local governments to apply information technology, which currently is very mature to be ableto realize the government is clean and transparent. Starting with building a complete database (datacenter),followed by developing applications that require each local government office and eventually builtan executive information system that can generate strategic information needed to help make decisions.

Concrete structures obtain their strength and load carrying capacity from the compatibility of concreteâ€™scompression capacity and steelâ€™s tensile strength. When a structure is in service, the concretecompression strength can easily be measured with all kinds of equipment, both non destructive, semi anddestructive.While the methods of analysis concrete in existing buildings is fairly straight forward and widely known,the determination of reinforcement embedded in the concrete is a more complicated matter. Beside thesteelâ€™s tensile strength, the barâ€™s configuration is very important, since the load carrying capacity isdepending on it. One destructive method is to un-mantle the bars and observes and measures the sizesand configuration manually. This will involve not only skilled labor but is time consuming and costly.One technology to overcome these difficulties is the use of rebar locators. The measuring method is basedon the eddy-current principle with pulse-induction. Important data as concrete cover, bar configurationand bar size can be obtained. This paper will discuss the principles of rebar locators, and will include acase study where structural capacity is calculated based on non destructive testing

Total population increase therefore water supply requirement, irrigation water, as well as requirement ofresidential areas are also increase. Many ways in development of water resources management arerequired to fulfill future water requirement, and need minimizing land use changes. Integrated waterresources management planning based on river basins is required. Polices for water resourcesconservation program, exploitation of water resources and control of the waterâ€™s destructive force arerequired for optimizing water resources management. A holistic water resources management is requiredfor protecting, maintaining as well as increasing the value of water resources. According to WaterResources Law No. 7 year 2004, a water resources planning for a river basin has to prepare withparticipation of some stakeholders. Many program alternatives of water resources management will beproduced from a water resources management planning process. Thus, the ranking analysis of alternativeprograms needs to be proceeded. Decision Support System (DSS) with weighting optimization model is atool for helping to determine the rank of water resources development programs. The DSS technique needscriteria as basic for prioritizing water resources development programs. Determination weight for eachcriterion and score for each alternative water resources development program are required. Applicationof this model is a priority analysis of water resources development program from JRATUNSELUNA riverbasin for administration district Jepara, Kudus and Demak

Recently, the transmission of electric energy has been developed by insulated cable. The suitable materialas an insulated cable is LLDPE and HDPE. In order to understand the quality of insulation system, themeasuring of PD has done. PD could begin completely insulation failure (breakdown). Therefore, it is veryimportant to understand the characteristic of PD and the enclose event on it, because PD is a main factorwhich caused insulation failure.This paper presents the result of PD measurement in the laboratory that used needle-plane electrode. Itwas supported by equipments such as osiloskop Digital GDS 2104 GW Instek, HPF, and RC detector.Polymer sample that used in this research is LLDPE (Linier Low Density Polyethylene) and HDPE with 20x 4 x 25 mm3 dimension in each. Needle was made by steel (length 50 mm and diameter 1.15 mm), it wasstick to the polymer material. The distance between needle to the plane is 5 mm. The applied voltage foreach sample was 16 kVrms, 18 kVrms, 20 kVrms and 22 kVrms. The Taking of PD data was done in thefirst minute, 10th minute, 20th and so on until 180th minute.The measurement result shows that the characteristic of PD number and maximum charge as a function oftime and as a function of applied voltage inclined increasing both on LLDPE and HDPE. But, PD intensityin HDPE is higher than LLDPE.
